DIY Backsplash: How to Update Your Kitchen in a Flash

Use a notched trowel to apply mastic or thinset to your walls (the tile dealer can help you make sure you’re using a trowel with the right size notches, and help you figure out whether thinset or mastic is right for your project). Apply mastic or thinset to a small area – about the size of 8 tiles – and press your tiles in to set them. Spacers may also come in handy here so that your finished product is neat and straight.
